Gather the ingredients - * Chocolate cake mix (+ the ingredients listed on the box) * Chocolate chips * Sweetened Condensed milk * Chocolate syrup * Powdered sugar * Heavy cream * Cocoa powder * Mini chocolate chips
Prepare the cake mix according to the instructions on the packaging for a 9x13" cake pan.
During the last 5 minutes of baking, prepare the chocolate condensed milk by microwaving chocolate chips and condensed milk together in 30 second intervals, mixing well after each, until smooth.
Immediately poke holes in the finished cake, then pour the chocolate condensed milk on top.
Pour the chocolate syrup on top of the cake and then allow it to cool to room temperature. Once it has cooled to room temperature, cover and place in the fridge to chill for at least 4 hours.
Once chilled, prepare the chocolate whipped cream by adding the heavy cream, cocoa powder, and powdered sugar to the bowl of a stand mixer fitted with the whisk attachment. Whip on high speed until light and fluffy.
Evenly spread chocolate whipped cream across the cake and top with mini chocolate chips. Slice and serve.
